Can someone with better eye sight and brains tell me where in the Scott Catalogs I can find Scott # 10NB4 -10NB13. Not sure even exist in Scott, but that is the numbers Colnect gave me. I can find 1N-9N and 11N-16N, but no 10N.
10N refers to Russian occupation of East Germany. You will find 10N right before the listings for DDR regular issues. 10NB are located right before DDR semi-postal issues.
